Definitions

  • the invention relates to a method and device high voltage development, especially for electrostatic product application of coating, in particular in a projection of such a liquid or powdery product.
  • one or more electrodes brought to high voltage must be supplied electrically to create an electrostatic field between the sprayer and the object to be coated.
  • the voltage supplied to an electrode is of the order of several tens of kilovolts.
  • To power a electrode from mains or other source conventional voltage such as a battery of accumulators, so it is necessary to increase substantially the available voltage.
  • the current is generally limited to a few milliamps for safety reason and to limit the power electric consumed by the electrode, this power to be partially dissipated as heat in the device.
  • the electrical signal circulating in the strand of cables is periodic and in order to obtain a voltage of maximum output, we try to give it a frequency close to the resonant frequency of the voltage raising rectifier.
  • This frequency of resonance can be calculated based on the scheme electric of the step-up rectifier or determined during operation by measuring the voltage downstream of the input transformer of the lifting rectifier, which allows to take into account variations in this resonant frequency of a lift rectifier to each other and over time for the same rectifier.
  • Maximum output voltage determines the operating point of the device.
  • the invention solves this problem.
  • It relates to a process for developing a high voltage, especially for electrostatic application of coating material, of the type comprising the application at the input of a rectifier-lift of voltage of a periodic signal supplied by a unit low voltage, characterized in that it consists of continuously varying the frequency of said signal periodic so that the power ratio electric at the output of said lifting rectifier on the input power of said low voltage unit either maximum.
  • the invention also relates to a device high voltage generator, in particular for supplying an electrostatic projector of a product of coating, of the type comprising a low voltage unit whose output is connected to a rectifier-lift voltage to which it provides a periodic signal characterized in that it includes means for control of the frequency of said periodic signal in function of the ratio of electric power in output of said boost rectifier on power input of said low voltage unit.
  • determined output power, input power is minimal.
  • the input current and voltage are optimum for generating a voltage and a current of sufficient output without risking damage the device.
  • the frequency of the periodic signal is continuously adjusted so that the power is optimal whatever are the desired current and voltage and even if the conditions of use influence behavior of the device, such as a long use which can lead to overheating components and a modification of their characteristics.
  • a calculator is used to determine the most suitable frequency. He proceeds to from current and voltage values low voltage unit and current supply and voltage in the step-up rectifier. In a variant of the invention, all these values being programming, use and calculator are simplified.
  • a low unit voltage 1 is essentially constituted by a stabilized power supply 1 connected to the mains and delivering direct current and direct voltage adjustable to an electric current generator 3 periodic of frequency f controllable in frequency.
  • the stabilized power supply 2 could also have for current source a storage battery or any other source of current.
  • the electrical signal generated by the low voltage unit 1 is a square signal of constant shape minimizing first harmonics, i.e. a wave the as close as possible to a perfect sinusoid.
  • a filter 11 makes it possible to partially smooth this signal.
  • the amplitude of this wave is variable depending on the generator supply voltage 3 by stabilized feeding 1.
  • the periodic signal from the low voltage unit 1 is applied through a strand 4 of cables flexible conductors at the input of a rectifier voltage booster 5 comprising a transformer input 6 and a voltage multiplier 7.
  • the voltage multiplier 7 output is connected to a charging electrode 8 of a projector coating product electrostatic no represented.
  • the operator can choose to vary the voltage delivered to the electrode as a function of projection characteristics desired or in depending on the shape of the objects to be coated.
  • the stream also varies depending on the high voltage scent at the level of the electrode which depend on its environment, for example the distance from ground the closest. Component temperature influences also on their characteristics and therefore on the frequency of the periodic signal to obtain a given voltage. For all these reasons, the frequency f of the periodic signal delivered by the generator 3 is controlled by a computer 10.
  • the computer 10 determines the efficiency of the high voltage generator device constituted by the low voltage unit 1 and the step-up rectifier 5 as being the ratio of the power at the output of the rectifier 5 to the input power of the low voltage unit 1. More precisely, these powers are calculated from the values of the voltage (U HT) and the current (I HT) in the elevator rectifier 5 on the one hand and the voltage (U alim) and the current (I alim) of supply of the low voltage unit 1 on the other.
  • the voltage (U HT ) is measured at the output of the voltage multiplier 7 near the charging electrode 8. Its value, representative of the value of the high voltage available at the electrode, is made measurable through a resistance of measure 16.
  • U HT * is an input data item of the computer 10.
  • the current (I HT ) is measured upstream of the cascade in a conductor where an alternating current also flows from the transformer 6.
  • the component of the current flowing in the measurement line is continuous since it is equal to the current at the electrode 6.
  • I HT * be this value.
  • the continuous values U HT * and I HT * are images of the physical quantities to be measured U HT and I HT , they can be processed by the computer 10. We proceed by increment by varying the set frequency delivered by the computer 10 to generator 3 and maintaining the direction of the increment as long as the ratio increases and by reversing the direction of the increment as soon as this ratio decreases.
  • the current is minimal, which avoids dissipation dangerous thermal and iron / dielectric losses important.
  • the input power is minimal.
  • the power consumption of the device is so minimal, which has an economic advantage not negligible. Indeed, some installations industrial companies have a large number of projectors of coating products and, consequently, associated high voltage generating devices.
  • the calculator determines the power by simple multiplication. Increments of frequency can be applied every 200 milliseconds.
  • the invention is also applicable in the case where the quantities measured are periodic: the calculator 10 then works, as is known skilled in the art, integrating the difference of phase between voltages and currents. However, this requires more programming work important and a more powerful calculator.
  • the invention also makes it possible to operate a single low voltage unit with rectifiers risers of different types. Indeed, a resistor 12 is inserted in all rectifiers elevators. Each type of rectifier-lift corresponds to a resistance value 12. The resistor 12 is connected to the computer 10 which determines its value by a classic fall measurement Of voltage. When connecting the rectifier-lift 5 on the low voltage unit 1, the value of resistance allows the calculator to identify the type of rectifier-lift and fix the point of start of the value increment process theoretical frequency allowing a return optimal. The resistance value therefore makes it possible to immediately give generator 3 a value of frequency setpoint f close to the optimal value. The incrementation process takes place only on one reduced frequency range.
  • the optimal frequency is thus reached more quickly with each setting service of the device, and in particular during connection of rectifier-lift 5 to the unit low voltage 1. This identification can also serve for security or verification reasons compatibility between devices.
  • the measurement of resistance value 12 could also be performed by a feedback loop from the generator 3.
  • the invention has been represented with the low unit voltage 1 separated from rectifier-booster 5 and connected to this one by a strand 4 of flexible cables but it also applies to the case where these subsets are part of an integrated or compact system.
